f111b228e0 Fix re-parsing of previously parsed text 
If a Doc object had been previously parsed, it was possible for
invalid parses to be added. There were two problems:

1) The parse was only being partially erased
2) The RightArc action was able to create a 1-cycle.

This patch fixes both errors, and avoids resetting the parse if one is
present. In theory this might allow a better parse to be predicted by
running the parser twice.

Closes #1253.

354458484c WIP on add_label bug during NER training 
Currently when a new label is introduced to NER during training,
it causes the labels to be read in in an unexpected order. This
invalidates the model.

47a3ef06a6 Unhack deprojetivization, moving it into pipeline 
Previously the deprojectivize() call was attached to the transition
system, and only called for German. Instead it should be a separate
process, called after the parser. This makes it available for any
language. Closes #898.

d99a9cbce9 different handling of space tokens 
space tokens are now always attached to the previous non-space token
there are two exceptions:
leading space tokens are attached to the first following non-space token
in input that consists exclusively of space tokens, the last space token
is the head of all others.
